This has been a long time coming.
Michael Baltaks has provided compiles of RMD’s XPCOM components that are compatible with both Intel and PowerPC versions of OSX. Which means that Mac users can once again use the Remember Mismatched Domains extension.
I know this is good news for some and I suggest you heap the usual new RMD release praises on Michael. Here I’ll start: Michael, thank you sooo much for quelling the Mac lynch mob that was assembling outside. ;-)
A bit of other significant RMD news is that the source for RMD is now being hosted in Google Code. Now that RMD contains binary components I think that it is important that anyone who wishes to do so is able to easily review the code and compile it themselves if they so wish. This is even more important as those components are user contributed. The RMD project can be found here:
Finally, I think this version of RMD should work with the Thunderbird 3 alpha. (I’ve only tested on my Linux install so it would be great if anyone who tries it could report on their success in the comments).
